Videochat with alien dalvik does not work properly: the front camera is rotated 90° and of bad quality (on top of the image is a green-ish "ribbon". That behaviour is reproducible with various Android apps: I've tried WhatsApp, Skype, Skype Lite, Viber and even Opera with WebRTC.

Attached is the screenshot from my PC, the rotated image is from Xperia, it stays rotated 90° no matter the device's rotation:
example from WebRTC chat

I can confirm similar problems here. SailfishX with Whatsapp; my face is rotated on the recipients phone and the video - as well as audio - quality is low. Also, and most problematically, the app does not work reliably, both video and audio suddenly stops at times. I had intended a 45 min video call which I had to quit after 20 min because the video and audio had stopped working a couple of times. Audio only worked well though.

Same problem with the jitsi meet android app: both front and back cameras are rotated and with a green bar on the side.
Looking more carefully, actually it's not a green bar: the blue and red channel are actually shifted to the right in the image.

Same problem with le latest 2.something (sorry i forgot what version i was on) and with the 3.0.0.8 i just flashed.
